MU'I'QR FUEL.

T0 all whom it concern:

Be it known that I, Jorm J; MURPHY, a citizen of the United States, residingat Chicago, in the county of Cook and State of Illinois, ,have inventeda new and useful Improvement in Motor Fuel, ofwhich the following is a specification. I

My present invention relates to improvements in fluid fuels, and has special refer ence to theproduction of a fuel fluid which will be suitable for use in power generators of an internal combustion type, as well as for use in other connections where an easily vaporizable fuel is desired which is capable of practically complete combustion and which therefore will leave little or no solid or condensible products of combustion.

One of the main objects that l have had in mind is to produce a uniformly burning fu'elof the ordinary merchantable grades of materials without-the necessity of special refining or blendingoperations, and in this connection I have sought to employ ordinary commercial grades of alcohol as an element of a fuel. It has lon' been known that the combustion of alcoho produces an intensely hot flame, but by itself its vapor'izing characteristics require special consideration and treatment which has prevented alcohol by itself from becoming a fuel for in- .ternal combustion engines to any considerable extent. Again, commercial grades of. alcohol contain appreciable quant1ties' of water (5% or more) which interferes with the admixture of the alcohol with vaporizable materials having an oily nature;

has therefore been my object to compound a mixture of commercial materials in.;whi'ch-- the several-elements will thoroughly dissolve and unite, and which will, as awhole'when mixed,'constitu e a'vaporizable fuel of uniform and dependable combustion characteristics. -I attain the above objects by means of specific mixtures hereinafter setfforth and It will noted that throughout the divers specific formulae occur coal oil or I kerosene, which is of too low a flashpoint or volatilization, limit to be useful for fuelin internal combustion engines without special means for its use, benzole, and impure ben- ,zine, alcohol, and another in redient, such as other, or some substitute t erefor, only a small proportion of which is used, but which is employed for easily controlling the Application filed July 5,

1922. Serial no. 572,973,

My discovery consistsin ascertaining that a comparatively heavy petroleum derivative,

such as coal oil or kerosene is capable of complete solution with commercial alcohol employed by me are of the ordinary commercial variety, and the mixture thereof can be made so as to produce a vaporizable fluid fuel at less cost than the divers combinations of'petroleum oils, or petroleum oils and gas tar oils which have heretofore been offered to the public can be compounded. As an example of one formula involving my inven- 'tion, I mix forty partsof coal oil or kerosene, forty parts of benzole, twenty parts of com mercial alcohol and five parts of ether. As a variant of-this formula, the mixture may be made of forty parts of kerosene, thirty of benzole, five of light petroleum, known on the market as casing head, gasoline which is separated by distillation at temperatures between 110 and 168 Fahrenheit, five of ether and twenty of alcohol. Another formula consists of kerosene thirty parts, benzole thirty parts, alcoholforty parts and casing head ten parts. Again, a mixture may be made with casing head twenty parts, benzole forty parts, kerosene forty parts and alcohol twenty parts. only commercial but a low proof commercial alcohol may preferably be employed. A ain, a-satisfactory fuel can be compounde of equal parts of kerosene, ben'zole and alcohol.

notherformula involving the same principles for obtaining a satisfactory solution of various elements consists of kerosene as With this formula not forty parts, benzole twenty seven, parts, al-' cohol twenty-eight parts, to which is added two per cent of vanilline. Other formulae naphtha, ten parts, alco ol, twenty parts,

benzole, twenty parts, with two per cent assphtlein.

' \l Alcohol, twenty parts, ether, five arts,

benzole, thirty-five parts, kerosene, t irtyeight parts, with two parts assphtlein.

Theassphtlein mentioned 'in thetwo foregoing formulae may be either purchased, or compounded n the following manner: Take fusel oil which has been distilled and separated at temperatures between 234 and/238 degrees Fahrenheit, to which add a mixture of equal parts of alcohol 188 proof and benzole until the compound starts to turn blue.

The naphtha mentioned in the formulae disclosed in this application is a relatively light petroleum separated by distillation between the temperatures 190 and 320 Fahrenheit. Gasoline is of the same general character and is separated by distillation between. the temperatures of 158 and 364 Fahrenheit.

It will be seen from a careful perusal of the above formulae that a single physical principle is employed in their compounding which is, broadly stated, a miscible association of a petroleum product of an oily nature, such as coal oil or kerosene with a commercial alcohol containing an appreciable quantity of water can be secured by bringing these substances together in the presence of an unrefined coal tar product, commercially known as benzole to form a fluid of the desired physical characteristics.

What I claim new is:

1."A fluid fuel consisting of coal oil forty thirty parts, benzole thirty parts, alcohol forty parts and casing head gasoline as defined ten parts. I

4:. A fluid fuel consisting of casing head gasoline as defined twenty parts, benzole forty parts, kerosene forty parts and alcohol tweniiy. parts.

5. fluid fuel consisting of kerosene fifty parts, benzole fifty parts and alcohol fifty parts.

6. A fluid fuel consisting ofkerosene forty parts, benzole twenty-seven parts, alcohol fwenty-eight parts with two per cent vaniline. i

7. A fluid fuel consisting of kerosene forty parts, naphtha twenty parts, benzole twenty parts and alcohol twent parts 8. A fluid fuel consisting of kerosene forty parts; gasoline ten parts naphtha ten parts, alcohol twenty parts, benzole twenty parts with two per cent assphtlein.

9. A fluid fuel consisting of alcohol twenty parts, ether five parts, benzole thirty-five parts, kerosene thirty-eight parts with two parts assphtlein.
